So after the news this morning, someone put the beans, corn and wheat limit bid, right up until a minute before the open. Corn and wheat finish the day negative. They never traded the limit prices. WTF do these spoof bids do for market integrity? Perhaps it's time that the employees at the CBOT put down their crack pipes and had a think about market efficiency. They're probably already behind the Chinese exchange but maybe someone there might think about regulating the traders who are making the market a farce before the game is well and truly up.
